Britain's Charles III will address the German parliament on Thursday, becoming the first monarch to do so, on the occasion of his inaugural state visit as king.

Germany marks the first trip abroad for Charles since ascending the throne, which is being interpreted as a "strong gesture" to build post-Brexit ties with the continent.

Arriving for his three-day trip on Wednesday, he and Queen Consort Camilla were greeted with military honours at the Brandenburg Gate, the first time the iconic site had lent the backdrop for such a ceremony.

Germany delivered the 18 advanced main battle tanks after Ukrainian crews were trained to operate them, British broadcaster the BBC reported.

Eighteen is four more than previously agreed, according to news outlets.

German Defence Minister Boris Pistorius said the Leopards 2s “have made it into the hands of our Ukrainian friends as promised and on time.”

He added he was certain the Leopard 2s could “make a decisive contribution” on the frontlines of Ukraine’s war against the Russian assault.

US President Joe Biden has claimed that the decision by the UK’s main domestic security service to raise the terrorism threat level in Northern Ireland will not prevent him from visiting the region.

“No. They can’t keep me out,” Biden said on Tuesday when asked if the move by MI5 would affect his plans to travel to Northern Ireland next month.

The White House has yet to officially confirm the US leader’s planned trip to Belfast on the 25th anniversary of the Good Friday Agreement, which was signed on April 10, 1998.

The British Security Service (MI5) has raised the threat level in Northern Ireland from domestic terrorism to "severe," its second-highest category, meaning that attacks are highly likely.

Northern Ireland Secretary Chris Heaton-Harris announced the decision, based on an MI5 intelligence assessment, on Tuesday, saying that the terror level in Northern Ireland had been increased from "substantial" to "severe."

Humza Yousaf, a left-separatist who has pioneered anti-free speech legislation and lobbied for fewer white people in high office, will be sworn in as the leader of  Scotland on Wednesday.

Yousaf has succeeded Nicola Sturgeon as leader of the Scottish National Party (SNP), which leads Scotland’s devolved government — roughly equivalent to a U.S. State government — in coalition with the even further left Scottish Greens.

Ukrainian soldiers have been filmed alongside depleted uranium ammunition that Britain is supplying to their country for the fight against Russia.

The footage is contained in a documentary the UK Ministry of Defence (MoD) released Sunday as Ukrainian tank crews completed their training.
